I got one NVIDIA 1050 GPU installed ... load the 390 version of the drivers and go it going. I added a second and third NVIDIA 1050 GPU ... but they do not seem to be recognized by Ubuntu.

Have you tried running lspci | grep ' VGA ' | cut -d" " -f 1 | xargs -i lspci -v -s {} like explained by knb?

It would add some useful output to further diagnose the issue.

  • I removed the second GPU ... but I entered the above command and got the following:00:02.0 VGA compatible controller: Intel Corporation HD Graphics 610 (rev 04) (prog-if 00 [VGA controller]) Subsystem: Gigabyte Technology Co., Ltd HD Graphics 610 Flags: bus master, fast devsel, latency 0, IRQ 126 Memory at 2ffe000000 (64-bit, non-prefetchable) [size=16M] Memory at 2fe0000000 (64-bit, prefetchable) [size=256M] I/O ports at f000 [size=64] Capabilities: Kernel driver in use: i915 Kernel modules: i915 – Timothy Gardner Mar 19 '19 at 22:38

  • THE 1050 2GB GPU works in the pcieX16 slot. I moved the card from the pcieX16 slot to another pcieX1 slot and restarted and nothing shows on the screen. I put the GPU back in the pcieX16 slot and restarte and screen appears and all is working as it should again. Is something needed for the pcieX1 slots to start working? – Timothy Gardner Mar 20 '19 at 00:45
  • Most of the time PCIe X1 ports are physically shorter than PCIe X16 slots. Your card would require a PCIe X16 sized slot to plug in. – LizardMaster Mar 20 '19 at 16:03
  • Could you provide more information about your motherboard and CPU? – LizardMaster Mar 20 '19 at 16:03
  • If you still have the issue, try adding all relevant information as an edit to your original question. If you use the PCIe X1 with a riser; does your GPU have adequate power delivery? – LizardMaster Mar 22 '19 at 17:42
